Hand Press

A hand press/ Screw press which converts rotational force i.e. Torque into much larger linear force. Radius of the Handle = 40 mm Therefore Circumference (i.e. Distance moved in one revolution by handle) = 2 (3.14) (40) = 251.2 mm Pitch of the screw = 2.5 Mechanical advantage of the system = 251.2 / 2.5 = 100.48 Let us suppose a 2N force is applied on the handle. The resultant force would be amplified to 2 X 100.48 = 200.96 N This is what should happen ideally.
